CENTRIFUGAL MACHINE.

SPECIFICATION forming part of Letters Patent No. 410,942, datedSeptember 10, 1889.

Application filed November 22, 1887 Serial No. 255,909. (No model.)

Figure 1 represents an elevation of a por- I tion of my improvedapparatus with one of the cones in section, and Fig. 2 is a sectionthrough the central shaft with two of the cones in elevation.

The loaf-forms F are arranged within the drum or cylinder, each with itsapex radially directed toward the center of the centrifugal machine, sothat'the bottoms of the forms or of the sugar-loaves themselves restagainst the wall of the drum of the centrifugal machine. In the firstcase the loaf-form must be either entirely filled or a circular sievemade to enter the form until it comes in contact with thebottom of theloaf. These sieves can either be attached to the wall of the drum orloose circular sieves and thick perforated sheet-metal disks L S can beloosely laid on the bottom of the loaf in each form? In this case thedrum is provided with ribbed studs or projecting parts N, in a radialline to the loaf-tips, said parts N being of such height that they willcome in contact with the loaf; but as the parts N are of smallercircumference than "the outer periphery of the forms F they do not comein contact therewith. The round sieve and the perforated sheet-metaldisk, the latter serving to support the sieve, are laid in the loaf-formbetween the loaf and the stud N. Stud N must be of such size that it isable to carry the loaf. The perforated sheet-metal disk L is quiteloose, while the sieve S fits tightly into the loaf-form. The loaves arearranged in one or more rows, one above the other or alternately.Suitable bearings A are attached to the wall and bottom of the drum toserve as supports for the form before the centrifugal machine is set inoperation. After the machine has been set in operation each loaf willlay itself against its stud N and be held by the same, while the formwhich has no support in radial direction presses itself firmly onto theloaf, so that all loosening of the same or throwing out of the loaf isavoided. Fig. 1 shows the loaf under this compression from the form.

0 o o" are openings in the drum for leadin g off the liquor driven outof the loaf by the centrifugal action.

K K are loose rings which form the bearings for the tips or apexes ofthe forms, and are held by means of wedges, as shown at a.

The spaces R can be employed for admitting heated air to dry the loavesduring the operation of the machine, the space between the forms and theloose rings K in this case being well packed and the shaft provided withsuitable stuffing-boxes and a longitudinal bore.

The forms F, as shown, have openings 19' in their apexes, through whichthe heated air may act upon the sugar to dry the same. The heated airmay be directed to the space B through suitable inlets made through theshaft.

I claim- 1. In combination, the shaft, the drum, the radial forms, andthe rings K K on said shaft, having seats for the forms and arrangedupon each side of the same, with means for securing said rings to theshaft, substantially as described.

2. In combination, the shaft, the drum, the radially-arranged forms,having open inner ends, the rings, having seats for said forms, saidrings'being upon each side of the forms and at a slight distance apart,and'the hollow shaft having out-lets opening into the spaces between therings, substantially as described.

I11 witness whereof I have hereunto signed my name in the presence oftwo subscribing witnesses.
